Template Files</h1>
<p>To simplify the creation of CMSIS-Core device files, the following template files are provided that should be extended by the silicon vendor to reflect the actual device and device peripherals. Silicon vendors add to these template files the following information:</p>
<ul>
<li><b>Device Peripheral Access Layer</b> that provides definitions for device-specific peripherals.</li>
<li><b>Access Functions for Peripherals</b> (optional) that provides additional helper functions to access device-specific peripherals.</li>
<li><b>Interrupt vectors</b> in the startup file that are device specific.</li>

<p><b>Adapt Template Files to a Device</b></p>
<p>The following steps describe how to adopt the template files to a specific device or device family. Copy the complete all files in the template directory and replace:</p>
<ul>
<li>directory name 'Vendor' with the abbreviation for the device vendor e.g.: NXP.</li>
<li>directory name 'Device' with the specific device name e.g.: LPC17xx.</li>
<li>in the file names 'Device' with the specific device name e.g.: LPC17xx.</li>
</ul>
<p>Each template file contains comments that start with <b>ToDo:</b> that describe a required modification. The template files contain place holders:</p>
<table  class="cmtable">
<tr>
<th>Placeholder </th><th>Replaced with  </th></tr>
<tr>
<td>&lt;Device&gt; </td><td>the specific device name or device family name; i.e. LPC17xx.  </td></tr>
<tr>
<td>&lt;DeviceInterrupt&gt; </td><td>a specific interrupt name of the device; i.e. TIM1 for Timer 1. </td></tr>
<tr>
<td>&lt;DeviceAbbreviation&gt; </td><td>short name or abbreviation of the device family; i.e. LPC.  </td></tr>
<tr>
<td>Cortex-M# </td><td>the specific Cortex-M processor name; i.e. Cortex-M3.  </td></tr>
